Torch text does not work with python 3.9 despite pypi saying it works for 3.6+

🐛 Bug

Do the following on a new env:

conda create -n metalearning python=3.9
conda activate metalearning
conda install -y pytorch==1.7.1 torchvision==0.8.2 torchaudio==0.7.2 cudatoolkit=11.0 -c pytorch -c nvidia
conda install -y torchtext==0.8.0 -c pytorch

Expected behavior Expected is that one can import torchtext e.g.

import torchtext

error:

(metalearning) miranda9~/automl-meta-learning $ conda install -y torchtext==0.8.0 -c pytorch

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - torchtext==0.8.0 -> python[version='>=3.6,<3.7.0a0|>=3.7,<3.8.0a0|>=3.8,<3.9.0a0']

Your python: python=3.9

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

The following specifications were found to be incompatible with your system:

  - feature:/linux-64::__glibc==2.17=0
  - feature:|@/linux-64::__glibc==2.17=0

Your installed version is: 2.17

Thanks @brando90 for raising the issue. Yes, looks like the problem with Conda installation. could you please try with pip using version 0.8.1 (the supported version for 3.9, I will update the readme as well)

pip install torchtext==0.8.1

It seems to be same issue using Conda with audio/vision as well for pytorch version<1.9? CC: @seemethere CC: @mthrok, @NicolasHug

but I also need pytorch 1.9.x. Would that work? @parmeet

for pytorch 1.9.x you would need to install torchtext >=0.10.0. This one also supports python 3.9. If you try installing using Conda without explicitly specifying the torchtext version i.e conda install torchtext -c pytorch, I think you get the latest both for torchtext (0.10.1) and pytorch (1.9.1)
